Rusty Minty

A simplified Rusty rewrite of Minty. Provides a CLI utility to mint ERC721 NFTs under the Minty contract.

Assumptions:

• IPFS node running locally
• Hardhat installed

Getting Started

$ git clone https://github.com/bernardoaraujor/rusty-minty
$ cd rusty-minty
$ npm install
$ npx hardhat compile

Run on Ethereum Rinkeby Testnet

First, get some tokens on Rinkeby Faucet.

For readability, the example below sets a few environment variables:

• FILE: path to file to be uploaded to IPFS.
• WEB3_PROV: URL to Web3 provider. Ex.: Infura endpoint, or local Ethereum node.
• PRIV_KEY: the Minter account private key, without 0x prefix (warning: be careful!).
• TOKEN_OWNER: the address of the NFT owner. It could be Minter or different account.
• GAS_LIMIT: the max amount of Gas you're willing to pay to mint. The -g CLI arg is optional and defaults to 10000000.
• CONTRACT_ADDR: the address of the Minty contract on the chain.
• CONTRACT_ABI: path to Minty contract ABI artifact (.json). The -a CLI arg is optional and defaults to abi/contracts/Minty.sol/Minty.json, which is the standard (relative) path when compiling via Hardhat.

               -g $GAS_LIMIT \

Note: you should check the Tx hash on Etherscan to verify whether it was successful.

Note: you should pin your CID on your local node or some pinning service, otherwise it might disappear in the future.

Test on local Hardhat setup

You could also test on a local Hardhat setup.

First, start a Hardhat node:

$ npx hardhat node

On a new terminal, deploy the contract and take note of its address:

$ npx hardhat run scripts/deploy.js
Minty deployed to: 0x5FbDB2315678afecb367f032d93F642f64180aa3

Finally, run the CLI utility:

$ cargo run -- -i $FILE \
